MC9S08RD8DWE 개요
A microcontroller is a semiconductor device that integrates a processor core, program memory, data memory, peripherals, and input/output functions into one package. The S08 family belongs to the broader 8-bit microcontroller hierarchy and is intended for cost-sensitive embedded designs. MC9S08RD8DWE combines that controller role with 8 KB of Flash storage in a 28-SOIC package, making it suitable for small control loops, sensor conditioning, actuator control, and communication-interface applications.
The principal verified characteristics are the 8-bit architecture, 8 MHz operating frequency, and 8 KB Flash memory. The verified distributor description identifies the package as 28-SOIC, while another distributor result identifies the device as an S08 peripheral microcontroller and lists its package as SOP with gull-wing terminals. Additional electrical details such as supply voltage, RAM size, I/O count, timer resources, communication peripherals, temperature range, and memory map were not supplied in the verified data and must be confirmed from the manufacturer documentation before design release.
The MC9S08RD8DWE is appropriate for embedded products where the firmware footprint is modest and an 8-bit CPU is adequate. Typical design uses include industrial control modules, low-cost sensor nodes, simple motor or relay controllers, instrument front ends, and peripheral-control boards. The SOIC package supports conventional surface-mount assembly and is useful when a product requires through-board test access or compatibility with established PCB footprints.
Design work should begin by verifying the exact pinout, power requirements, reset behavior, clock configuration, peripheral multiplexing, and programming interface in the manufacturer datasheet. Because the supplied web evidence confirms only the device family, frequency, Flash capacity, and package, engineers should not infer unlisted electrical limits or peripheral availability. Firmware migration also requires checking memory compatibility, vector-table behavior, and toolchain support.
This product record combines verified distributor identity and package information with an explicit separation between confirmed facts and unavailable specifications. It is intended to help engineers identify the correct MCU, locate source documentation, and plan validation, while avoiding unsupported assumptions about timing, power, compliance, or lifecycle status.

일반적인 애플리케이션
MC9S08RD8DWE 적합 용도: 6 애플리케이션s: Low-Cost Sensor Node, Simple Relay and Actuator Controller, Instrument Front Panel, Low-Cost Motor Control Board, Peripheral Control Module, Embedded Educational Controller.
Low-Cost Sensor Node
MC9S08RD8DWE fits compact sensor-node designs where an 8-bit controller is sufficient for acquiring digital or discrete sensor signals and coordinating local actions. The verified 8 MHz operating frequency provides a straightforward control platform, while 8 KB of Flash can hold a focused acquisition, filtering, threshold, and reporting routine. The device should be selected only after confirming the required sensor interface, GPIO count, timing, and supply limits in the manufacturer documentation. Its 28-SOIC package also supports conventional surface-mount assembly and board-level test access. For low-power designs, power-consumption modes, wake sources, and analog resources must be verified before layout release.
추천
Simple Relay and Actuator Controller
MC9S08RD8DWE can serve as the central controller in a small relay or actuator board because an 8-bit MCU can execute deterministic state-machine logic, debounce inputs, drive outputs, and implement basic interlocks. The verified 8 MHz clock is useful for straightforward control-loop timing, and the 8 KB Flash capacity is appropriate for compact firmware when the application does not require extensive data logging. The design must verify output-driver ratings, isolation requirements, inductive-load protection, reset behavior, and pin multiplexing before connecting external hardware. A 28-SOIC package can simplify rework and automated inspection compared with a very fine-pitch package, although the exact footprint still requires confirmation.
Instrument Front Panel
MC9S08RD8DWE is a plausible candidate for an instrument front panel that handles buttons, indicators, local display updates, and supervisory logic. Its 8-bit architecture is appropriate when the primary work is state management rather than intensive signal processing, and the verified 8 KB Flash supports a compact user-interface and control firmware. The exact number and electrical type of I/O pins were not supplied, so the panel layout must be checked against the complete datasheet pinout. Display drivers, debounce timing, watchdog behavior, communication with a measurement engine, and supply sequencing should be verified before committing the MCU. Firmware development should also confirm supported programming and debug tools.
추천
Low-Cost Motor Control Board
MC9S08RD8DWE may fit a basic motor-control or stepper-sequencing board when the system uses discrete drivers and relatively modest timing requirements. The verified 8 MHz S08 core can execute command decoding, motion-state sequencing, limit handling, and diagnostic reporting. However, the supplied data does not confirm timer channels, PWM outputs, comparator resources, or pin assignments, so those functions must be validated before design selection. Motor systems also require verification of transient protection, isolation, ground strategy, current sensing, and thermal margins. The 28-SOIC package is useful for prototypes and serviceable assemblies, but its electrical footprint should be compared with the motor board's available land pattern and assembly process.
추천
Peripheral Control Module
MC9S08RD8DWE can be used in a small peripheral-control module that converts external commands into device configuration, status reporting, and fault handling. The verified 8-bit format and 8 KB Flash are suitable for a compact command interpreter and peripheral state machine, provided the required serial interface and I/O resources are confirmed. Engineers should verify protocol timing, interrupt requirements, buffer strategy, watchdog use, and programming connector requirements in the manufacturer documentation. The 28-SOIC package supports a straightforward through-hole-style visual inspection workflow and can be useful where a product must be serviced or manually replaced. Because lifecycle and lead-time data were not supplied, procurement planning should include a current NXP or authorized-distributor check.
추천
Embedded Educational Controller
MC9S08RD8DWE is suitable for educational and evaluation boards that demonstrate an 8-bit embedded-control architecture, Flash programming, GPIO handling, interrupts, and basic peripheral interaction. The verified 8 MHz S08 core and 8 KB Flash make the device approachable for compact labs and low-cost teaching platforms. A board designer should still verify the exact pinout, programming connector, debug access, supply requirements, and supported toolchain in the manufacturer documentation. Add test points, accessible power rails, and a standard expansion interface where practical so students can observe signals without redesigning the board. For production teaching equipment, validate lifecycle availability and regulatory requirements separately from the technical MCU selection.

설계 노트
Confirm the MC9S08RD8DWE supply-voltage range and I/O limits from the manufacturer datasheet before placing the device in a board power scheme. The supplied data does not include voltage thresholds, current consumption, or power-mode specifications. Route local decoupling close to the device pins according to the manufacturer recommendation, and verify the regulator's transient response against the MCU's digital and analog supply requirements. Treat any power calculation as incomplete until those missing values are verified.
Use the verified 28-SOIC package identity as the starting point for PCB layout, but obtain the official package drawing before defining the land pattern. Confirm pin numbering, pin names, exposed-pad status, and the recommended assembly footprint. Preserve access to any programming, reset, and clock pins required by the selected toolchain. Because the supplied evidence does not provide the complete pinout, do not route power or signals from assumptions based on a generic SOIC footprint.
Do not substitute a similarly named S08 device based only on package similarity. A valid replacement must match the 28-SOIC footprint, pin functions, clock requirements, Flash and RAM resources, interrupt behavior, supply limits, and programming model. The supplied comparison search did not establish a complete equivalent for MC9S08RD8DWE, so verify the manufacturer datasheet and test firmware on the candidate before production use.
규정 준수 정보
